Then read along, the radio hardware (70cm wideband user transceiver
and 13cm transceiver components) are also documented in said conference
procedings :-)
6cm transceiver building blocks by Henning DF9IC were published
over the last year or so in the ADACOM magazine.

Windoze :-) But don't despair, there's only one modem anyway and
it is undergoing some significant redesign. Once it will be wider
available, I'll hack a Linux driver... should be very easy,
a 20 liner or so in baycom.c...

More info (a revised schematic diagram and kits) will be available
from baycom sometime soon (the schematic will be free, the kits
not :-))
